Title: Improvements in processing carbon black-rubber mixes
IPC: C08K5/42
Filed: 1954-09-14
Abstract: A vulcanized product is prepared by heating a mixture of synthetic rubber, a relatively large amount of carbon black, and a relatively small amount of an aromatic sulphonyl chloride, at at least 275 DEG F., thereafter incorporating vulcanizing and other ingredients, shaping, and vulcanizing.  Specified synthetic rubbers are polymers of butadiene and isoprene and their copolymers with isobutylene, styrene, alphamethyl styrene, ethyl or methyl acrylate, methyl methacrylate, actylonitrile, methyl vinyl ketone, methyl isopropenyl ketone, and monovinyl pyridine. The aromatic sulphonyl chloride may be represented as RSO2Cl, where R is phenyl or naphthyl, substituted or not by one or more alkyl, nitro, acetylamino, or ester groups, or halogens, e.g. benzene sulphonyl chloride, p-toluene sulphonyl chloride, p-nitrobenzene sulphonyl chloride and naphthalene b -sulphonyl chloride, and 1 to 3 parts per 100 of synthetic rubber is preferably used.  U.S.A. Specification 2,118,601 is referred to.ALSO:A vulcanized product of high electrical resistivity and low torsional hysteresis is prepared by heating a mixture of natural or synthetic rubber, a relatively large amount of carbon black, and a relatively small amount of an aromatic sulphonyl chloride, at a temperature of at least 275 DEG F., thereafter incorporating vulcanizing and other ingredients, shaping, and vulcanizing.  The aromatic sulphonyl chloride is preferably of an amount of 1 to 3 parts per 100 parts of natural or synthetic rubber, and may be represented as RSO2Cl where R is a phenyl or naphthyl-group, or a phenyl or naphthyl group substituted by one or more alkyl, nitro, acetylamino, or ester groups, or halogens, e.g. benzene sulphonyl chloride, p-toluene sulphonyl chloride, or p-nitrobenzene sulphonyl chloride, &c.  In an example 100 parts Hevea rubber, 50 parts carbon black, and 5 parts stearic acid are mixed in a Banbury mixer or on a two roll mill, and 2.2 parts p-nitrobenzene sulphonyl chloride added at a temperature preferably below 275 DEG F.  The mill temperature is raised to 300 DEG F. and the mixture masticated for 10 minutes. Thereafter the mill is cooled to 150 DEG  to 200 DEG F., and 2 parts pine tar, 2 parts zinc oxide, 1 part antioxidant, 1 part accelerator, and 2.6 parts of sulphur are added.  The mixture is then vulcanized 45 minutes at 287 DEG F.  Other examples are described illustrating the use of butadienestyrene copolymer, isobutylene-isoprene copolymer, p-toluene sulphonyl chloride, p-nitrobenzene sulphonyl chloride, and naphthalene beta sulphonyl chloride.  U.S.A. Specification 2,118,601 is referred to.

Title: Improvements in and relating to paper reel joining mechanism
IPC: B65H19/18
Filed: 1949-10-18
Abstract: 684,765. Feeding webs. WITTON-JAMES, Ltd., BRADSHAW, R., TAYLOR, H., and RALPH, F. W. Jan. 18, 1951, [Oct. 18, 1949], No. 26763/49. Class 100 (i). Reel-joining mechanism to effect a join between a web-running into a printing press and the web of a replacement roll, comprises two electric generators responsive respectively to the speeds of the press and the expiring roll, each generator producing an output function, such as a voltage or frequency, varying with the generator speed and applied in opposition to control the operation of a member, or two members adapted to operate sequentially, thus initiating an operation required to effect reeljoining, or initiating two such operations in sequence. As shown, a D.C. generator P, driven at a substantially constant speed from a printing press, excites one coil of a pair of differential relays A, B connected across the generator terminals through potentiometers Pa, Pb. Similarly, a generator R, driven by the expiring roll, excites the other coils of the relays operating in opposition to the first coils through potentiometers Ra, Rb. During expiration of the reel being fed to the press, the voltage produced by the generator P is higher than that produced by the generator R, such that the relays are inoperative until the speed of the generator R so increases as to cause, through the increased voltage, the reversal of one of the relays, thus causing its contacts to initiate the preliminary stages of a reel-joining operation, i.e., the contacts cause rotation of a reel-carrier to bring the replacement reel into reel-joining position, and cause acceleration of this reel, e.g., by driving belts. When the expiring reel has been accelerated, the further increase in speed of generator R causes the reversal of the second relay B, the contacts of which then automatically initiate operations for the completion of the reel-joining operations, i.e., contacting the expiring web with the replacement reel which carries adhesive, such that it is fed into the press with the expiring web which is then severed. In a modification, A.C. generators replace the D.C. generators, their outputs being separately rectified to operate the relays directly or indirectly through thermionic valves which in this case operate electro-magnetic relays. In a further modification, the outputs of each of a pair of A.C. generators provides a variable frequency converted into a varying A.C. voltage by a reactance, such voltage being applied, preferably after rectification, directly to a relay or indirectly through a thermionic valve operating a relay.

Title: Improvements in rotary pumps
IPC: F04D29/18
Filed: 1928-09-24
Abstract: 318,026. Dehn. F. B., (Auto-Prime Pump Co.). Sept. 24, 1928. Centrifugal pumps.-A rotary pump has removable, mating, pump rings 21, 22, in the impeller chamber 13, forming a channel 23 which communicates with an inlet 24. Fig. 2, and outlet 25, and an impeller 20 extending into the channel 23. A priming chamber 12 is provided or the chamber 13 may be enlarged for this purpose. The outlet is connected to a reservoir which is first partly filled with liquid. This flows through a trickle port 31, held open by a light spring 32, and charges the priming chamber until the pump has raised the level in the reservoir high enough to close the valve 31. When the level falls the valve 31 opens so that if the pump has lost its prime it will be replenished. The thickened rim 45 of the impeller is formed with buckets 47 cut by a rotating grinding disc 51, Fig. 5, with rounded rim 52 arranged at an inclination with one diameter tangential to the periphery of the impeller and the diameter at right angles thereto parallel to the plane thereof. The corners 48 are also rounded. The channel 23 is wider at its inner portion 72, Fig. 10, than at its outer 73 and the faces 60 may have inclined grooves 68, Fig. 7, to prevent inward leakage from the channel 23. To vary the capacity of a pump, rings 21, 22 with channels 23 differing in size are used.

Title: Camera film feed mechanisms
IPC: G03B1/60
Filed: 1975-07-01
Abstract: 1461063 Camera mechanisms BALDA-  WERKE PHOTOGRAPHISCHE GERATE UND KUNSTSTOFF GmbH & CO KG 1 July 1975 [12 March 1975] 27633/75 Heading G2A A camera film feed and shutter cocking member includes two coaxial independently rotatable cog wheels, one for film feed and one for shutter cocking, and a toothed member movable into and out of coupling engagement with said cog wheels. As shown, the film feed wheel 1 has a coaxial cog wheel 2 fixed thereto, with a similar wheel 3 rotatably mounted thereon. Wheels 2 and 3 can be coupled together by a cog wheel 4 on one end of a toggle lever 10. Fig. 1 shows the mechanism in the cocked position. The cocking lever 5 has been pivoted anti-clockwise, against spring 21, by one of a number of cocking pins 16 on the underside of a cog wheel 9 as it rotates clockwise. It is so rotated by engagement with the anti-clockwise rotation of wheels 2 and 3 by rotation of the filmwinding wheel 1, wheels 2 and 3 being coupled together by wheel 9. As it pivots anti-clockwise, lever 5 pushes a slide 11 to its extreme left position. A lug 17 on the slide lies in a widened region of a slot 20 in toggle lever 10, which is pivoted so that wheel 4 is out of engagement with wheels 2 and 3. A detent 6, fixed on a pin 19 which passes through a slot 11b in slide 11, is biased clockwise by a spring 15 so that in the cocked position of Fig. 1 its rounded head 6a rests in one of a number of locking recesses 8 in the upper surface of wheel 9. When the shutter release 22 is depressed, a rod 24 is pushed downwards. Lever 5, which is pivoted to rod 24, also moves downwards to slide free of pin 16. It is now pulled clockwise by a spring 21, so that it strikes and actuates a shutter blade 28 to effect an exposure. Slide 11 is also now pulled to the right by a spring 15. Movement of lug 17 in slot 11b causes lever 10 to pivot so as to bring wheel 4 into coupling engagement with wheels 2 and 3. As wheel 1 is now rotated to advance the film, wheel 9 is also rotated, so that eventually the head 6a of detent 6 rides out of the recess 8 and on to the surface 7. Thus a nose 12 on detent 6 locks lever 10 in the Fig. 3 position. With further rotation of wheel 1, lever 5 is engaged by one of the pins 16 and pivoted anti-clockwise back to the Fig. 1 position. Slide 11 is pushed back to the left, and the Fig. 1 position is reached once more.

The pivoting movement is limited by virtue of the non-circular shapes of the pivot pins 11 and of the tapered resilient twin bushes 10, which in their unstressed condition have adjacent empty spaces 12, 13, Fig. 8, and which by deformation offer progressively increasing resistance to rotation. This resilient arrangement provides a progressive effect of vibration damping for the cables. Pins 11 and mating parts may have cross-sections of alter-  native non-circular form, e.g. rectangular, and the assembly may alternatively have four or  more arms.

[Also in Group XXVIII] Charging of a battery of coke ovens from a plurality of coal bunkers 1, Fig. 1, mounted on a wagon, not shown, travelling on rails 28 on the oven cover 29 is effected through hoppers 2 each having a telescopic extension sleeve 50, Fig. 7, which fits into the oven aperture, an internal coal guide 51 and a plurality of coalsupporting rods 53 hinged about horizontal axes 52 and which when released allows the charge to fall into the oven. The hinged ends of the rods are located externally of the hopper and have bent-over portions contacting rollers 54 which when displaced upwardly release the rods. Dust-laden gas is drawn from the base of each hopper 2 through pipes 3 leading to a manifold 4 which discharges below the level of liquid, e.g. water or waste oil in a bath 5 and from which washed gas passes through a duct 20 into a cyclone 21 and thence to the intake of a fan 23. The separated particle outlet of the cyclone also dips into a bath 15 connected by pipes 13, 14 to bath 5; bath 15 being supplied from a feed 6 through pipes 7, 18, and bath 5 being supplied through pipes 7, 9 leading to a jacket 10 surrounding a perforated portion 12 of the manifold 4. Discharge is effected through valved pipes 48, 49 and a channel 17. In a modification, each suction-pipe discharges to the underside of a bed of coke or coal subjected to a water or oil spray, and contained in a chamber mounted in front of the bunker associated with each pipe.
